Embodiment Construction

[0010] A thermal transfer adhesive for metal shells, made of the following raw materials in parts by weight (kg): acrylic resin (AR-2630) 15, E-42 epoxy resin 25, polyethylene glycol 8, butene two Acid anhydride 4, ethylene glycol 10, tert-butyl hydroperoxide 2, polyoxyethylene oleate 10, polyvinylpyrrolidone 8, crosslinking agent TAIC 2, coumarone 6, 1-hydroxyethyl-2-oil imidazoline 2, dibutyl phthalate 6, 1,2-cyclohexanediamine 3, acetone 60, xylene 40.

[0011] The preparation method of the thermal transfer adhesive for the metal shell comprises the following steps:

[0012] (1) Put E-42 epoxy resin, polyethylene glycol, maleic anhydride, and ethylene glycol into acetone, heat to 75-85°C, then add tert-butyl hydroperoxide, oil Acid polyoxyethylene ester, stirred for 30-40 minutes, then added crosslinking agent TAIC, coumarone, reacted for 40-50 minutes, raised the temperature to 120-130°C, added 1-hydroxyethyl-2-oleyl imidazole phylloline, stirred and reacted for 3 hours;...

Abstract

The invention discloses a heat transfer printing adhesive for a metal shell. The adhesive is prepared from the following raw materials in parts by weight: 12-15 parts of acrylic resin (AR-2630), 20-25 parts of E-42 epoxy resin, 8-12 parts of polyethylene glycol, 4-6 parts of maleic anhydride, 8-10 parts of ethylene glycol, 2-3 parts of tert-butyl hydroperoxide, 8-10 parts of oleic acid polyoxyethylene ester, 5-8 parts of polyvinyl pyrrolidone, 1-2 parts of crosslinking agent TAIC, 4-6 parts of coumarone, 2-3 parts of 1-hydroxyethyl-2-oleic imidazoline, 4-6 parts of dibutyl phthalate, 2-3 parts of 1,2-diaminocyclohexane, 55-60 parts of acetone and 40-45 parts of dimethylbenzene. Compared with the prior art, the adhesive is used for transferring a pattern on the metal shell, has the advantages that the adhesive is firm in bonding and enables the product not to break, shed or yellow easily, and has the effect on improving the product quality. The crosslinking agent TAIC is added in the formula, thus greatly improving the crosslinking property of various components, improving the bonding strength and improving the weatherability through initiation and polymerization of an initiator. 1-hydroxyethyl-2-oleic imidazoline enables the corrosion resistance to be greatly improved.

Description

technical field [0001] The invention relates to a thermal transfer adhesive, which belongs to the field of printing materials. Background technique [0002] Thermal transfer printing is to directly contact the patterned transfer film with the substrate, and the graphic layer on the transfer film is melted and transferred to the substrate. The thermal transfer film includes a carrier layer, a release layer, a protective layer, an ink layer, and an adhesive layer. The coatings are closely related and affect each other. Among them, the bonding layer is the substrate adhesive used to bond the ink information layer and various materials, and must have high adhesion, high temperature resistance, scratch resistance, water resistance, cooking resistance and chemical resistance performance. In the prior art, there are many cases of printing patterns on metal shells such as metal cylinders and metal boxes, but due to the quality problems of thermal transfer adhesives, the scratch re...
